Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusion on classification
Classification relevant information:
Water solubility: 5.9 mg/L at 25 °C, pH 5 (OECD Guideline 105, flask method)
Degradation: Biodegradation: Not readily biodegradable (11% after 28 d, OECD 301 B)
Bioaccumulation: Log Kow = 2.53 at 25 °C, pH 5.5 (EU Method A.8 - Appendix 1, Estimation method)
Aquatic acute toxicity
Fish: LC50 (96 h) >32.23 µg/L (Danio rerio, OECD 203, measured geometric mean)
Aquatic invertebrates: EC50 (48 h) >11.28 µg/L (Daphnia magna, OECD 202, measured geometric mean)
Algae/aquatic plant: ErC50 (72 h) >56.58 µg/L (Desmodesmus subspicatus, OECD 201, measured geometric mean)
Aquatic chronic toxicity
Fish: No data available
Aquatic invertebrates: No data available
Algae/aquatic plant: EC10 (72 h) >56.58 µg/L (Desmodesmus subspicatus, OECD 201, measured geometric mean)
Classification according to CLP
Aquatic toxicity data are available for three trophic levels (fish, aquatic invertebrates and algae). No hazard was indicated up to the highest test item concentration. Based on the data above, the substance is not considered to be rapidly degradable in the environment and the potential of the substance to bioaccumulate is low. Therefore the substance does not need to be classified and labeled according to the consolidated version of Regulation (EC) No 1272/2008 and all further amendments (ATPs).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
